Error ORA-22835 when executing a query for Report Definition

SA-45759

Summary



ORA-22835 error occurs when executing a query for a Report Definition.


Error Messages



There was a problem getting a list: code: 22835 SQLState: 99999 Message: ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 13146, maximum: 4000)


Steps to Reproduce

  1. Create a Report Definition
  2. Refer a property (Column: CLOB).
  3. Run the report.


Root Cause



A defect or configuration issue in the operating environment.

A database is limited to 4000 bytes in a VARCHAR2 column. When the property value length is greater than 4000, a CLOB column must be used. However, support for a CLOB was not available until Pega 7.2.2.



Resolution



Perform the following local-change:
  1. Set the reporting/retrieveFullClobContent Dynamic System Setting (DSS) defined on Pega-RULES to True.
  2. Install HFix-37641.
  3. Restart the server.
After performing the local-change, delete the distinct clause from the query if the below error occurs.

ERROR - Not returning connection 8 for database "pegadata" to the pool as it previously encountered the following error
(rd.queryexec.SqlQueryExecutor) ERROR - An error occured on executing the query for the report definition - There was a problem getting a list: code: 932 SQLState: 42000 Message: ORA-00932: inconsistent datatypes: expected - got CLOB
